Front, anternnular and supra orbital angles, and epistome all acutely spinous; anterolateral border armed with 4 acute spines.
Carapace thin, disk-like, covered with little short bristles which leave certain symmetrical raised linear patches bare. The meropodites of legs are clad in the same way, and have two long bare stripes. The front, the antennular supra-orbital angles and the epistome are all acutely spinous. The anterolateral border of the carapace is armed with 4 acute spines. The middle of the upper border of the orbit is more or less serrate. The eyes are large and reniform. The chelipeds vary according to age and sex, but the arm and wrist are always armed with spines; the palm is smooth, nude, oval and somewhat compressed and the fingers are short, blunt, hollowed at tip. In the adult male the palms, or one of them are remarkably deep. The anterior border of the moropodites of all the legs are armed along its whole length with remarkably large and even spines, the posterior border ends in a spine.
